E-Book

I bought an ebook Practical Enterprise Risk Management and it doesn't work . The digital library says in progress. How LONG???? I tried to call them and their phone are not working. I have assignments waiting for me. I want a full refund because what's the use of me paying for something that does not work and YES I did follow the instructions on how to download an ebook from takealot. IT's disappointing time consuming. They can send me a hard cover I don't care. I AM GOING TO GET MY MONEYS WORTH
